East/West

East/West is a market term used to describe price differentials, demand dynamics, and flow patterns between Eastern and Western regions, most commonly Asia versus Europe or the Atlantic Basin. In energy markets, East/West spreads are a critical indicator of where marginal demand is strongest and where supply is most constrained. These spreads influence crude oil flows, refined product exports, LNG cargo movements, and freight economics. For example, when Asian demand is strong relative to Europe, East/West crude spreads may widen, incentivising barrels to move eastward despite longer shipping times. East/West dynamics are shaped by refinery utilisation, seasonal demand, freight rates, inventory levels, and geopolitical factors such as sanctions or trade restrictions. Traders monitor East/West spreads to identify arbitrage opportunities and assess regional imbalances. Persistent changes in these spreads often signal structural shifts in demand growth or supply availability. As global energy markets become increasingly interconnected, East/West pricing relationships play a central role in aligning regional markets and determining global trade flows.
